BAG HOLDER.

' 7 Application filed July 23,

1 My invention relates to packing "and storing vessels and especially to holders for receptacles that areto be filled with grain and the like. It has for its'objects the production of an automatic holder'for bags, in particular, by means of which an empty bag maybe supported from a standard or scale,filled, and then when the desired weight or fullness of the bag is reached, the same may be tripped and allowed to fall on the platform and the holder released for further use. I attain my object by providing a pair of parallel rods carrying a pair of toggles, each comprising a lazy tong structure pivoted on the adjacent ends of the two rods, so that when the latter are moved toward and away from each otherthe projecting free ends'ot the tongs will open and close, whereby they may be conveniently engaged within the four corners of the bag-and by drawing the parallel rods together may forcibly hold the same against disengagement, as by projecting points extending through the walls of the bags. The parallel rods are normally drawn together by tension springs, and when filling is complete may be locked bymeans 01 a swinging hook pivoted on one rod and when the two are drawn together adapted toengage and lock the other.

Y My invention is illustrated in the accompanying drawings, in which I Fig. 1 is a perspective view of the device complete, with a bag shown in dotted lines in the engaged position; I

Fig. 2 is an end view of the structure of Fig. 1 with the locking hook tripped, the springs pulled down by the weight of the filled bags and the latter just being disengaged from the holder; and

Fig. 3 is a detailed view of a modification showing the upper rod of the device provided with adjustable end bearings for the tongs, whereby the latter may be set for different sizes of bags or other receptacles.

Referring to the drawings and'particularly to Figs. 1 and 2, 12'are a pair of parallel rods carrying on opposite ends parallel pairs of lazy tongs 34'having' points '5 on the ends of their free projecting members adapted to engage within the corners of a bag ,6. \Vhen the rods 1-2 are pulled apart, the points 5 are retracted toward each other as shown in Fig. 2, and when they are spread out they engage the bag as shown in Fig. 1. The latter is the position while loading or filling and at such times the parallel rods 1926. Serial No. 12 L433.

1-2 are drawn together by the springs 9 10 and may be locked against disengagement from the bag by the hook 7 pivoted on the upper rod and latching around the lower rod. The lazy tongs 3 I pivoted at the two points 1'1 and at their outer ends 11 in a manner wellunderstood in the art, so that when the rodsfare moved up and down, toward and away from each other the pivots 11 will approach and recede,causing the members t i to swing around the pivots 11 and retract their'points 5, as heretofore stated. The lazy tongs '4: is constructed in'a similar manner with members P 9.

' To suspend the device from a steelyard S as shown in Fig. 2 or from a rigid support if desired, any suitable attaching device may be provided such asa chain suspension 8. The

strength of thesprings 9-'1O may be regulateddso as to yieldonly to a certain weight or tension, so thatfor example it the device isto be used withthe standardbag of wheat or some other grain of which theweight is known, the springs 910 may be so constructed as to yield to that weight exactly, no more and no less. In such case, the latch 7 need not be employed, but the springs take the place of steelyards, permitting the device to open when the bag is filled to the requisite amount, and releasing the same on the platform automatically. Otherwise the operation would be as shown in Fig. 2, totrip the latch '7 when the steelyard S shows the desired weight. Where the device is to be used for variable weights the springs 9-10 are made weak enough to yield to the smallest weight, and strong enough to normally close the lazy tongs 34 when idle.

Referring to Fig. 3, the rod 2 is shown with its ends threaded, and fitted with sleeves 10 having lock nuts 12 and outside bearing nuts 11". The upper arms 3-l" of the two lazy tongs 34 are shown in this figure, and itis obvious that by loosening the nuts 11 the sleeves 10 may be set in or out to accommodate comprises members 3 -3 any size bag. The operation and the rest or the construction is the same as in Fig. 1.

Having thus described my 1nvent1on, what .I claim is:

1. A loading support for receptacles comprising symmetrically arranged pairs ofpar- 1 allel projecting members adapted to engage lazv ton s and the connectin rods have tension springs normall drawing them together so as to spreac apart the proyecting members of the holding means.

a. The device claimed in claim 1, in which the connecting rods have a detachable latch member adapted to secure them together and lock the projecting members in engagement with a receptacle. '5. The device claimed in claiml in which the connecting rods have transverse toggle frames pivoted on their opposite ends, and tension springs connected to said rods and normally drawing the same toward each other.

6. The device claimed in claim 1, in which theconnecting rods have at their opposite ends parallel pairs of toggle levers, or lazy tongs, each having a pair of free projecting points to engage withthe bag orother receptacle, and said points adapted to moved toward and away fromeach other when such parallel rods are moved away from or toward each other respectively. p

' 7. The device claimed in clami 1, in which the holder is normallymaintained in engagement with a receptacle by means of a tension spring adapted to support a predetermined weight of material and when that weight has been deposited in the receptacle to tree the same from the holder automatically.

9. A bag holder as claimed in claim 1 comprising a pair of parallel rods wit-h threaded ends, movable sleeves adapted to be adjusted and locked in position onsaid ends, transverse toggle levers or lazy tongs With'free projecting ends pivoted on said rods against said sleeves, and means forholding saidtoggle leversin position. v 1 i Intestimony whereof I here-unto my signature. i I Y 1 WILLIAM BRADFORD HEBBARD.
